WINDING-TOOL FOR BALE-FASTENINGS.

SPECIFICATION forming part of Letters Patent No. 630,825, dated August 8, 1899. Application filed September 19, 1898. eri ND- 691,365. (No model.)

To all whom it may concern:

Be it known that I, DOUGLAS M. CAMPBELL, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented a new and useful Winding-Tool for Bale-Fastenings, of which the following is a specification.

the same very tight.

While the present invention contemplates a tool designed particularly as a winding-tool for bale-fastenings, it also has for an object the provision of a novel and efficient tool capable of general use as a ratchet-wrench for any purpose to which it can be applied.

The invention has for a further object the provision of a winding-tool or Wrench having simple and efficient means for relieving the binding strain on the tool after the key or other object has been tightened to the desired degree, so that it can be readily released or disengaged from the key or other object at any angle or position.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure 1 is a side view of a winding-tool or wrench embodying the improvements contemplated by the present invention. Fig. 2 is a front view thereof. Fig. 3 is a sectional view on the line 3 3 of Fig. 1. Fig. at is a detail sectional view on the line 4 4 of Fig. 2. Fig. 5 is a similar view on the line 5 5 of Fig; 2. Fig. 6 is a detail sectional view showing the hanger connection with the toolshank.

Referring to the accompanying drawings, the numeral 1 designates the main supporting shank or arm of the tool, and this shank not only provides for carrying the different working parts of the tool, but also provides a support or hanger therefor, as will be hereinafter more particularly referred to.

The main supporting-shank 1 of the tool is preferably provided with a channeled face 2 in its front side and extending substantially the entire length thereof, and at one end the said shank'is bifurcated and provided with the separate spaced parallel circular bearingcollars 3 and 4., which provide a bearing-sup port for the revoluble ratchet socket-head 5. The revoluble ratchet socket-head 5 loosely registers within the bearing-collars li and 4 of the tool-shank 1 and is provided at one end with a flange or head 6, engaging at one side of the collar 3, and at its other end with a threaded neck 7, projecting through an opening in the bearing-collar 4 and receiving thereon a securing-nut 8, arranged at one side of said bearing-collar at and exterior thereto to provide, in conjunction with the flange or head 6 at the opposite end of the socket-head, for holding the socket-head 5 in its bearings and preventing longitudinal displacement thereof.

The revoluble ratchet socket-head 5,1nounted for rotation in the bearings at one end of the shank 1, has formed therein a squared socket 9, which is specially designed to fit over or receive the winding-key of a bale-fastening of the type disclosed in my patent herein referred to, so as to provide means for rotating the winding-key and tightening up the bale-band in the manner fully explained in the patent but it will of course be understood that the socket 9 can be fitted on nuts or any other object should it be desired to use the tool as an ordinary wrench.

At the end fitting in the bearing-collar 4 the revoluble ratchet socket-head 5 is provided wit-h a reduced guide opening or bore 10, the function of which will be presently referred to, and in its exterior surface the said socket-head is provided with separate concentric ratchet-rings 11 and 12, the ratchetring 12 lying within the circular plane of one of the bearing-collars of the shank, (designated by the numeral 4,) while the other ratchet-ringll of the socket-head lies within the circular plane of the pawl-carrying ring 13, formed at one end of the oscillatory leverhead 14.

The oscillatory lever-head 14. is arranged for a swinging movement at one side of the shank 1 adjacent to its bifurcated end, and the pawl-carrying ring 13, formed at one end of said head, loosely encircles the socket-head 5 and registers in the bifurcation of the shank, between the two bearing-collars 3 and 4 thereof. The oscillatory lever-head 14 has formed therein, at one side of the ring 13 thereof, a pawl-recess 15, having a rounded bearing portion 16, in which is loosely seated the rounded pivot end 17 of a propelling-pawl 18. This propelling-pawl 18 is provided with a beveled engaging point 1 9, which normally projects out of the recess 15 inside of the ring 13, so as to engage with the ratchet-ring ll of the revoluble socket-head, and leading off from the pawl-receivin g recess 15 is a springsocket 20, in which is seated one end of a spiral or coilspring 21, the otherend of which engages a nose 22, projecting from one side of the pawl 18, opposite its point, and said springprovides for normally holding the pointin ratchet engagement with the ratchet-ring 11, so that as the lever-head 14 is swung in one direction the socket-head 5 will be rotated therewith, while-the opposite movement of the lever-head will carry the point of the pawl loosely over the ratchet-teeth forming the ratchet-ring 11. At the end opposite its pawl-carrying ring 13 the oscillatory leverhead 14 is provided with a socket portion 23, in which is'secured one end of a lever-handle 24, arranged atone side of the main shank l, and when not in use adapted to lie within the channeled face 2 thereof, and held in such position by meansof an open ,U -shaped spring-clasp 25, secured fast at its closed end to one side of the shank 1. While the clasp 25 provides for holding the lever-handle alongside of the shank 1' when not in use, still said clasp does not interfere with the leverhandle being readilydrawn downward to operate or rotate the ratchet socket-head 5.

To provide for holding the revoluble soc-kethead 5 against rotation when the propellingpawl 18 is traveling back over the ratchetteeth 11 to take a new hold in such teeth, a check-dog 26 is employed. This check-dog is arranged to work within a pawl-recess 26, for-med in the bearing-collar 4, within which is disposed the ratchet-ring 12, and has the point end normally held in engagementwith the teeth of said ratchet-ring 12 through the mediumof a spring 28, arranged in a springopening 29, leading into the recess 26 and held in place by means of a cap-plate 30, detachably fastened tothe exterior of the bearing-collar 4 over the said spring-opening 29. lVith the ,spring 28 normally holding the dog 26 in engagement with the ratchet-tin g 12, it will readily be understood that said dog will positively prevent backward rotation of the socket-head, so that the bale-band being tightened cannot unwind on the key engaged by the socket-head; but when the winding operation is complete it is desirable to release the dog 26 from engagement with the ratchet-ring 12, and the means for accomplish-' ing this result will now be described' The check-dog 26 is mounted at its pivot end on a rock-pin 31, the inner end of which works in the bearing-collar 4, and the outer end of which projects through a bearing-plate 32, secured to the outer side of said collar, and said outer projecting end of the rock-pin 31 has secured fast thereto one end of a swinging trip-lever 33, the other end of which trip-lever is provided with a laterally-widened curved contact-shoe 34, which has a registering contact with the tapered surface of a longitudinal movable releasing-cone 35. The releasingcone 35 is provided at its apex'with a short supporting-stern 36, working in the guide opening or bore 10 in one end of the socket 5, and at its opposite end the said cone is provided with a sliding sihan'k 37, werking through a guide-opening 38, formed in one end of an angled supporting-bracket 39, i he other end of which bracket is rigidly fastened, as at 40, to one side of the lever-head 14 ,soas

to move therewith. Thesupporting-bracket' 39 is provided with a bifurcation, pivotally recei-vin g therein the intermediate portion of a lever 41, one end of which loosely engages an opening 42 in the shank '37 of the cene and the other end of which has loosely connected thereto one end of the operating j g or wire 43. The pivotal lever 41 is provided at one side of its pivot with a fork 44, which receives therein the free end-of an adj ustingspring 45, the other end .of which spring is secured fast to the supporting-bracket 39, and the purpose of said spring is to hold the cone -35 normally in such a position as not to affect the engagement of the check-dog ,36 with the ratchet-ring 12.

The operating rod or wire 43 is around the lever-handle 24 to form aslideloop 46, and one terminal of said rodor wire is extended laterally from the levershandle to form a pull-arm 47, which is engaged byithe finger of the operator when it is desired to release the check-dog. It will be nnderstood that after the winding of the bale band has been completed, by exerting a pull ,on the pull-arm 47 the operating rod .or wire 43-is drawn in adirection causing [the pivotal lever 41 to oscillate on its intermediate pivot and move the releasing-cone 35 in a direction toward the socket-head carried by-the hearings 3 and 4. This movement of the releasing cone 35 willcause the inclined snr-faceof said cone to press against the contact-shoe :34 of the trip-lever 33, thereby imparting a rocking movement to ,the rock-pin 31, and consequentl y throwing the checkrdog 26 outof engagement with the ratchet-ring 12, thereby relieving the strain upon the tool andloosening up the socket-head 5 from its engagement with the winding-key of the balerfastening or other object, so that the tool can be readily slipped ofi of said key or other object irrep ct t f t ang po t on t my pccupy. This isa very important feature of the invention in order to permit the ready disengagement of the socket 5 from the winding-key or other object.

When the tool is designed for heavy work, the same is necessarily constructed too large and heavy to be conveniently carried about by an operator, and it is therefore necessary to provide means for suspending the same within convenient reach of the operator, and to provide for this the main supporting-shank 1 of the tool is formed at its upper ends with a hanging loop a8, which is engaged in the hook 419 of a suitable hanger 48. This hanger forms no part of the present application, and only a sufficient portion thereof is illustrated to show the operative relation between the same and the winding-tool; but it will further be understood that any suitable type of hanging device may be employed to provide for properly suspending the tool within convenient reach of the operator, so that when it is desired to use the same it is simply necessary for the operator to engage the sockethead 5 with the winding-key and then move the lever-handle 24 alternately downward and upward to provide for rotating said head.

From the foregoing it is thought that the construction, operation, and many advanlages of the herein-described winding-tool will be readily apparent to those skilled in the art without further description, and it will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
